I fear this is related to #define SLAPD_DYNACL being under #ifdef
LDAP_DEVEL in HEAD; I think I tested with #undef LDAP_DEVEL in HEAD, but
not yet in RE23 because that test was not present yet. Based on earlier
discussion, I'd move #define SLAPD_DYNACL outside #define LDAP_DEVEL.
I'll test everything in a moment, and be back soon.
